Vibratory backfilling device for on-ridge transplant

Abstract

A vibratory backfilling device includes a mounting frame, vertical base plates, cam link mechanisms and a soil beat actuator. The entire backfilling device is mounted on a rear cross beam of a transplanter, and follows the transplanter to move forwards between ridges; two sides of the mounting frame are connected to the vertical base plates respectively, and the cam link mechanism is mounted on the vertical base plate; and the soil beat actuator is rotatably arranged on the vertical base plate, an upper end of the long plate inclines towards an inner side of the vertical base plate and is hinged to a link rod of the cam link mechanism, and the soil beat actuator is driven by the cam link mechanism and continuously vibrates and beats two sides of the ridge to cause ridge soil to flow back and backfill a hole of the pot seedling.

What is claimed is: 
     
       1. A vibratory backfilling device for on-ridge transplant, comprising: a mounting frame, vertical base plates, cam link mechanisms and a soil beat actuator, wherein the mounting frame serves as a machine frame of the entire vibratory backfilling device, is mounted on a rear cross beam of a transplanter, and follows the transplanter to move forwards between ridges; two sides of the mounting frame are connected to the vertical base plates respectively, the cam link mechanism is mounted on the vertical base plate, and the cam link mechanism comprises a cam, a roller, a slidable push rod, a preload spring, and a link rod; the cam is located at an uppermost end of the vertical base plate and is connected to an output shaft of a drive motor, a top of the slidable push rod is provided with the roller, and the roller is arranged to press against the cam; the slidable push rod is capable of moving up and down in the vertical base plate, a lower end of the slidable push rod is hinged to one end of the link rod, the other end of the link rod is hinged to the soil beat actuator, one end of the preload spring is fixedly connected to the vertical base plate, the other end of the preload spring is connected to the slidable push rod, and the preload spring is used for providing upward acting force for the slidable push rod to make the roller at a top end of the slidable push rod press against the cam constantly; and the soil beat actuator is a long plate, a middle of the long plate is rotatably arranged on the vertical base plate, an upper end of the long plate inclines towards an inner side of the vertical base plate and is hinged to a tail end of the link rod, and the soil beat actuator is driven by the cam link mechanism and continuously vibrates and beats two sides of the ridge where a pot seedling is just planted so as to cause ridge soil to flow back and backfill a hole of the pot seedling. 
     
     
       2. The vibratory backfilling device for on-ridge transplant according to  claim 1 , wherein a straight notch is provided in the vertical base plate, and a shaft for hinging the slidable push rod to the link rod is located in the straight notch. 
     
     
       3. The vibratory backfilling device for on-ridge transplant according to  claim 1 , wherein a length of the link rod is adjustable. 
     
     
       4. The vibratory backfilling device for on-ridge transplant according to  claim 3 , wherein the link rod is of nested design, and comprises a link rod sleeve and a link rod shaft, the link rod shaft is mounted in the link rod sleeve, a plurality of slots are provided in the link rod sleeve in a length direction, and the length of the link rod is adjusted by adjusting the link rod shaft to be correspondingly and fixedly connected to the slots at different positions in the link rod sleeve. 
     
     
       5. The vibratory backfilling device for on-ridge transplant according to  claim 1 , wherein the soil beat actuator is configured in a spade-like shape, a reinforcing rib is arranged in a middle of the soil beat actuator, and two side plates are bent towards the middle at an angle. 
     
     
       6. The vibratory backfilling device for on-ridge transplant according to  claim 1 , wherein the mounting frame is a rectangular frame and is fixed to the rear cross beam of the transplanter through bolts. 
     
     
       7. The vibratory backfilling device for on-ridge transplant according to  claim 1 , wherein the drive motor is fixed to an outer side of the vertical base plate.
